Flashcard 30 - Math Flashcard Set for the SAT Exam

Slope of \(L_{2} = \frac{2}{3}\)

Slope of \(L_{3} = -\frac{3}{2}\)

Parallel lines have equal slopes while perpendicular lines have slopes that are negative reciprocals of each other. If a line has slope \(a\), lines parallel to it will have the same slope, \(a\), and lines perpendicular to it will have slope \(-\frac{1}{a}\).
